Unable to read the firmware version from L96M33 via UART

Hi,
We are using L96M33 module in our project. We are interfacing the sensor with STM32WB microcontroller via UART. But we are unable to read the firmware version from the module. Query used to get the firmware version: $PQVERNO,R*3F\r\n. But not received any response from the L96 module. We are using 9600 as baud rate with stop bits as 1 and parity is none. Below is the hardware interface with microcontroller:

Request your support in resolving the issue.

Thanks,
